Method Detail

comparator

public LongComparator comparator()

Description copied from interface: Long2LongSortedMap

Returns the comparator associated with this sorted set, or null if it uses its keys' natural ordering.

Note that this specification strengthens the one given in SortedMap.comparator().

Specified by:

comparator in interface Long2LongSortedMap

Specified by:

comparator in interface SortedMap<Long,Long>

See Also:

SortedMap.comparator()

long2LongEntrySet

public ObjectSortedSet<Long2LongMap.Entry> long2LongEntrySet()

Description copied from interface: Long2LongMap

Returns a type-specific set view of the mappings contained in this map.

This method is necessary because there is no inheritance along type parameters: it is thus impossible to strengthen Long2LongMap.entrySet() so that it returns an ObjectSet of objects of type Map.Entry (the latter makes it possible to access keys and values with type-specific methods).

Specified by:

long2LongEntrySet in interface Long2LongMap

Specified by:

long2LongEntrySet in interface Long2LongSortedMap

Overrides:

long2LongEntrySet in class Long2LongMaps.EmptyMap

Returns:

a type-specific set view of the mappings contained in this map.

See Also:

Long2LongMap.entrySet()

entrySet

public ObjectSortedSet<Map.Entry<Long,Long>> entrySet()

Description copied from interface: Long2LongMap

Returns a set view of the mappings contained in this map.

Note that this specification strengthens the one given in Map.entrySet().

Specified by:

entrySet in interface Long2LongMap

Specified by:

entrySet in interface Long2LongSortedMap

Specified by:

entrySet in interface Map<Long,Long>

Specified by:

entrySet in interface SortedMap<Long,Long>

Overrides:

entrySet in class Long2LongMaps.EmptyMap

Returns:

a set view of the mappings contained in this map.

See Also:

Map.entrySet()

keySet

public LongSortedSet keySet()

Description copied from interface: Long2LongMap

Returns a set view of the keys contained in this map.

Note that this specification strengthens the one given in Map.keySet().

Specified by:

keySet in interface Long2LongMap

Specified by:

keySet in interface Long2LongSortedMap

Specified by:

keySet in interface Map<Long,Long>

Specified by:

keySet in interface SortedMap<Long,Long>

Overrides:

keySet in class Long2LongMaps.EmptyMap

Returns:

a set view of the keys contained in this map.

See Also:

Map.keySet()

public Long2LongSortedMap subMap(long from,
                                 long to)

SortedMap.subMap(Object,Object)

headMap

public Long2LongSortedMap headMap(long to)

Description copied from interface: Long2LongSortedMap

Returns a view of the portion of this sorted map whose keys are strictly less than toKey.
